This crowded group shot is the result of a four-pack available in the Universe line in 2004. In the back is Stockade, a blocky treaded artillery bot that is a redeco of the 2001 Vehicon Tank Drone from Beast Machines, now repurposed as an individual Autobot. In front of him with the big horn on his head is Magna Stampede, who turns into a mechanical unicorn. He's a redeco of Battle Unicorn, also from 2001 Beast Machines. In the foreground, left side, is Mini-Con Prowl, part of the Emergency Mini-Con Team from 2003's Armada. And on the left is Terradive, originally part of the Air Military Mini-Con Team, also from Armada 2003.
The combined form of the Universe Micromaster Aerialbots is Superion, an amalgamation of six robots plus their pack-in accessories that serve as connectors, head, and extremities of the gestalt warrior. While in Japan, the original source of the design ( Sixwing , 1992) was available in a collected set, this combiner needed to be purchased one bot at a time in the 2007 Universe release.
